This dataset was recorded on a farm near Jondaryan, South East Queensland in March 2018 during a training exercise. The track mostly covered fallow ground but ventured into a mature sorghum crop for a few meters on the eastern edge. The logger recorded an EM reading every 0.2 seconds and a GPS reading every second. The EM38 instrument was properly calibrated for quad-phase readings but may not have been for in-phase. The intent of the exercise was to measure soil water content. The soil type at this location is a Black Vertosol under the Australian Soils Classification (Isbell, 2002).
